That means the waterway has been without flowing water for 113 days as of Friday.

Magirl said stream-flow records indicate this is the fifth-longest no-flow period on Sabino Creek since measurements began in 1932, with the other four occurring in recent decades. The longest period of continuous dry days was 165, ending in March 2006.

Magirl said it will take about an inch or more of rainfall, or snowmelt from the nearby Catalina Mountains, to get the creek flowing again.

The long-term outlook for the creek and vegetation in the canyon remains uncertain.
